Recruiting PHASE1, PHASE2 Obstructive Sleep Apnea

New treatment option for Obstructive Sleep Apnea

Official title Rescue Pharmacotherapy for OSA

ClinicalTrials.gov ID: NCT05293600

What this study is testing

What is Acetazolamide?

Acetazolamide is an investigational medicine, being studied as a potential treatment for obstructive sleep apnea.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
Persistent obstructive sleep apnea (OSA) is common in people treated with mandibular advancement device (MAD) or hypoglossal nerve stimulation (HGNS). For most patients, these treatments are the last line of defense.
